BACKGROUND OF THE INVENTION

Sinks are commonly used in kitchen, bathroom, utility, and commercial applications for washing and cleaning. Various types and styles of sinks have achieved widespread application in residential and commercial markets. Typically, a sink comprises a faucet attached to a wash bowl like fixture comprising a drain which can be closed or opened using a drain plug. One of the common problem with the conventional sink is the debris or stain left on the inner surface the sink after use. Often the faucet doesn't provide a sufficient way to clean the sink, especially the inner surface of the sink, so one must splash water with their hand, wipe the sink clean with a cloth or a paper towel in order to clean the entire sink.

In certain cases, detachable type faucets are used for cleaning the sinks by spraying pressurized water through spray jets, but involves less cleaning efficiency and manual directing of faucets. In addition, sinks are also developed with electric pumps to spray water thus eliminating the need for faucets, however these sinks are needed to be sufficiently filled with water and cannot remove tough stains from sink surface.

Accordingly, there exists a need for an improved sink capable of self-cleaning or easy rinsing of the sink surface with pressurized water along with a cleaning liquid by simple actuation of a button or a lever switch.

The present invention relates to a self-cleaning sink, comprising a plurality of water spray injectors disposed on inner face beneath an upper rim of the sink, adapted for delivering pressurized water to the interior of the sink and a plurality of conduits adapted to carry a cleaning liquid from a reservoir to one or more of the water spray injectors. An actuator adapted for diverting the water flow from a faucet to the water spray injectors. The self-cleaning sink further comprises an activation control linked to a faucet, adapted for pumping a predefined amount of the cleaning liquid through at least one conduit delivered to the inner surface of sink via plurality of water spray injectors.

In an embodiment, the self-cleaning sink further comprises a holder made of materials such as a wire mesh or basket for holding the reservoir containing the cleaning liquid. Further, the plurality of water spray injectors are substantially distributed under the upper rim of the sink so as to deliver pressurized water all over the inner bowl of the sink. In an embodiment, the cleaning liquid from the reservoir is mixed with the pressurized water delivered to the inner bowl of the sink for rinsing off the stains and debris.
